Move Vagrantfile into the box

[thom8]

Rather than requiring a custom Vagrantfile it would be nice if this was moved into the box so a new project can be initialised by just vagrant init DrupalMel/beetbox; vagrant up

The biggest issue I see with this is being able to reference the project root dir from the box Vagrantfile.

I often use vagrant ID to reference VM's see vagrant global-status. eg vagrant destroy [ID]

This could be run inside another project so traversing the current location to find the closest Vagrantfile won't work.

So the approach I plan to work on will be as such:

• If the command was invoked with an ID
  • Determine the ID by iterating over ARGV and extracting the most logical value
  • Run vagrant global-status into a ruby variable
  • Use regex to extract the working directory
• Else
  • Iterate over the current directories until the Vagrantfile is found

The second part is already written, but will likely need some modifications: https://github.com/Realityloop/packer-templates/blob/realityloop/ubuntu-12.04-x86_64/example/Vagrantfile#L7

I have a proof of concept for the first that, that if you put it in your Box Vagrantfile and run vagrant status [ID] you will get a result (but it will also break your box, so remove it after testing it):

output = `vagrant global-status`
puts /#{ARGV[1]}.*?(\/.*?)\n/.match(output)[1]
exit

Updated PoC:

# Find the Vagrant ID if supplied.
id = nil
ARGV.each do |arg|
  id = arg[/\h{7}/] ? arg : id
end

# Determine the current working directory.
cwd = nil
if id != nil
  cwd = /#{id}.*?(\/.*?)\n/.match(`vagrant global-status`)[1]
else
  paths = Dir.pwd.split('/')
  while cwd == nil
    dir = paths.join('/')
    current = paths.pop
    if File.exists?("#{dir}/VagrantFile")
      cwd = dir
    end
  end
end
puts cwd
exit

That works in the project dir, a sub-dir and from anywhere via use of the ID
